The conical flask is not rinsed before performing titration because doing so could dilute the solution and alter the concentration, affecting the accuracy of the titration. It is important to maintain the concentration of the solution as accurately as possible for precise results.
What else can I help you with?
Why is it important to remove the CO2 from the solutions before doing the titration?
Removing CO2 from solutions is important in titration to prevent it from reacting with the analyte or titrant, which can introduce errors in the results. CO2 can also affect the pH of the solution, leading to inaccurate titration endpoints. By removing CO2, you ensure the titration is more precise and reliable.
Is it necessary to rinse the conical flask with some standard solution of oxalic acid before use?
I believe it is necessary to rinse the conical flask with oxalic acid before use, unless you are sure that the conical flask is really clean and dry before use. However to prevent having any types of unwanted chemical reaction when you pour the oxalic acid in the flask, it is best to rinse it with oxalic acid before use, so that there will not be errors like e.g. there is no pinkish color formed in the solution when you add the color indicator in the oxalic acid when doing titration.
How do you get an accurate titration?
In Titration, to make sure we get a reliable and accurate result at first we will do a rough titration and we would do this by balancing the weigh boat to 0.00, use exact 2.5g of potassium carbonate, make sure the stopper your using is not broken and test it before using it. Look carefully at position of meniscus and it should be read from eye level. Raising the burette and glass pipette for every activity will help to reduce contamination, by doing these procedures we will get accurate results. After 25.9 cm make it drop by drop, to reduce the human error, there should be more than one person to do the experiment so they can get the timing right. Before using the conical flask, water it with distilled water
When doing a titration in chemistry why do you weigh by difference?
Weighing by difference involves weighing the sample before and after the titration to calculate the amount of substance used. This method is used to accurately determine the amount of substance added or reacted in the titration process, accounting for any losses or impurities that may have affected the final result.
What is the point of doing a titration?
Titration is used to determine the concentration of a substance in a solution by reacting it with a known concentration of another substance. It is a common technique in chemistry for quantitative analysis and can help in determining the unknown concentration of acids, bases, and other substances.

Why were you instructed to keep swirling the flask?
To mix the reactants. Assuming you have been doing a titration experiment and I am doing your homework its so as you add the acid/alkali you can accuratly close the biuret when the indicator changes colour.
How do ask correct sentence what you were doing from before?
The correct sentence is the following: "What were you doing from before?"
What is the correct sentence to ask what you were doing from before?
There are different ways to write this sentence. The best way to write it would be "What were you doing before this"?
What does prerecorded mean?
Pre-Recorded Means That Your Doing It Before. You Record A Show On T.v. Your Doing It Before Not After
What happen if you adding water to the titrated substance in the conical flask during the process of titration?
NoUser 1Yes. By adding water to rinse, you will be changing the concentration of the thing you are titrating, and so your calculation will be off. If you have material on the walls of the flask, just gently stir the flask and let the solution in the flask wash anything off the walls.User 2I do not believe this is true. Once you add an amount of reactant into your flask adding more water will not change the number of moles of reactant that are present in the flask. The titrant will react in the mole ratio for that particular reaction so water doesn't play a role. You can rinse the flask and even use water to get part of a drop into your flask for a more accurate titration.User 3No. User 1 means to say that water in the volumetric burette or pipette will effect the concentration of titrant moles. Water in a conical flask will not effect the titre values because the same mole ratios are reacting, and your titre value is measured from the volume remaining in the volumetric burette and not the conical flask. User 2 is correct, although using water to rinse the volumetric burette's contents into the conical flask would adversely effect the results, as volumetric burettes and pipettes are designed to account for the few remaining drops in the instruments. Shaking or tapping the instruments is also a bad idea, as they can easily be broken and doing this would effect your titre values anyway.User 4It will not affect the result at all as long as you use distilled water, as just tap water obviously contains other minerals etc that will affect the results.
When doing laundry, do you put detergent in before or after clothes?
Detergent should be put in before adding clothes when doing laundry.
